NU-SETI: A Proposal to Detect Extra-Terrestrial Signals Carried by Neutrinos

Abstract

Recent observations of changes in radioactive decay rates associated with the annual variation of the Earth-Sun distance, with solar rotation, and particularly with solar storms, suggest that radioactive decay rates may be responding to small changes in ambient neutrino/antineutrino flux. We propose to build a network of detectors (NU-SETI), based on monitoring radioactive decays, to search for pulsed signals from an extra-terrestrial source carried by neutrinos or antineutrinos.
